Localization is a mandatory requirement in Wireless Sensor Networks (WSNs). Many solutions focus on static networks and do not account for mobility. In this paper we present an extension of the Monte Carlo Localization method, which exploits the mobility behavior of certain applications in WSNs to reduce the localization error. Our approach called PO-MCL maps regular traveled paths of nodes to an...
Although operating as groups is required by many of ad hoc applications and privacy preservation is a critical issue in such scenarios, there is only a sparse research done on anonymous multicast routing in MANETs. Anonymity, location privacy and unlinkable communication are important privacy aspects specially in wireless environments. A potential eavesdropper may launch traffic analysis to infer...
Localization in Wireless Sensor Networks (WSNs) denotes the procedure of a single sensor node to determine its geographical position in space. As these nodes are limited in computational power, battery lifetime and communication range, there is the requirement for efficient localization algorithms which is an ongoing topic in research. Nearly all algorithms are based on the usage of seed nodes which...
Distance measurement between neighboring nodes in Wireless Sensor Networks (WSNs) is a rudimentary requirement for localization and position estimation algorithms. Common techniques exploit the signal strength to estimate the distance between two nodes. Although this has been widely accepted in research during the last two decades, practical evaluations of these techniques in outdoor scenarios under...
